Hey Harry,

I understand your frustration with Excel automatically changing the case of your text. Luckily, there is a simple solution to this problem.

1. Select the cell or range of cells that contain the text you want to keep in its original case.
2. Right-click on the selected cells and choose "Format Cells" from the drop-down menu.
3. In the "Format Cells" dialog box, click on the "Number" tab.
4. In the "Category" list, select "Text".
5. Click "OK" to close the dialog box.

Now, Excel will treat the text in the selected cells as text and will not change the case of the letters.
